In the following, a charging stand 100 for a vacuum cleaner 200according to embodiments of the present disclosure will be describedwith reference to FIGS. 1 to 16. The charging stand 100 may charge thevacuum cleaner 200, for example, a rechargeable vacuum cleaner.

As shown in FIGS. 1-16, the charging stand 100 for a vacuum cleaner 200according to embodiments of the present disclosure includes a body 1, apedal 2 and a safety protection device 3.

A blade 4 is provided in the body 1 and is configured to cut off hairsor the like around a brushroll 201 of the vacuum cleaner 200 placed onthe charging stand 100. In such a case, the charging stand 100 not onlyhas a charging function but also is able to clear off hairs or the likewound around the brushroll 201, thereby expanding the functionality ofthe charging stand 100, facilitating the cleaning of the brushroll 201,and simplifying a cleaning process of the brushroll 201. It should benoted herein that when a cleaning function of the charging stand 100 isapplied, the vacuum cleaner 200 may be configured as a rechargeablevacuum cleaner or other types of vacuum cleaners.

Optionally, the blade 4 extends linearly along a length direction of theblade 4, as shown in FIG. 7, such that the processing is simple and thecost is low. Certainly, the blade 4 may extend curvedly along the lengthdirection thereof, such that in a hair-cutting process, the stability ofthe blade 4 can be effectively ensured, and hence the hair-cuttingeffect of the blade 4 is better. For example, the blade 4 extends in anarc manner along the length direction thereof. For example, referring toFIG. 1 in combination with FIGS. 11 to 13, the blade 4 is bent towards adirection away from a center of the body 1. Specifically, the blade 4deviates from a central axis of the brushroll 201 but is bent in adirection towards a center of the brushroll 201, so as to cut off thehairs wound around the brushroll 201 smoothly. Certainly, the blade 4may extend in a wavy manner along the length direction thereof (notshown), such that the stability of the blade 4 may also be guaranteed inthe hair-cutting process and the blade 4 is not easily deformed.

The pedal 2 is provided on the body 1 and is pivotable between a firstposition and a second position. An opening 21 is defined in the pedaland corresponds to the position of the blade 4. When the pedal 2 is inthe first position, the blade 4 is located below the opening 21 (asshown in FIG. 2); when the pedal 2 is in the second position, the blade4 extends out of the opening 21 (as shown in FIG. 3). When the pedal 2is in the first position, the blade 4 is received in the body and is notexposed from the opening 21. At this time, the rechargeable vacuumcleaner can be placed on the charging stand 100 to be charged, and thesafety is guaranteed when the charging stand 100 is in use. When thepedal 2 is in the second position, the blade 4 extends out of theopening 21. At this time, the vacuum cleaner 200 is actuated to rotatethe brushroll 201, such that the blade 4 may cut off hairs or the likewound around the brushroll 201 effectively.

One safety protection device 3 may be provided, or a plurality of safetyprotection devices 3 may be provided. When there is one safetyprotection device 3, the safety protection device 3 is disposed on thebody 1 and normally engaged with the pedal 2. When the safety protectiondevice 3 is toggled, the safety protection device 3 is disengaged fromthe pedal 2 to make the pedal 2 move from the first position to thesecond position.

When there are a plurality of safety protection devices 3, at least twosafety protection devices 3 are disposed on the body 1 and spaced apartfrom each other, and each safety protection device 3 is normally engagedwith the pedal 2. When the at least two safety protection devices 3 aretoggled, the at least two safety protection devices 3 are disengagedfrom the pedal 2 to make the pedal 2 move from the first position to thesecond position. In normal situations, the safety protection devices 3are engaged with the pedal 2 to keep the pedal 2 in the first position,that is, the blade 4 is located within the body 1, which may effectivelyprevent a safety risk that the user may be injured because the pedal 2directly moves to the second position with the blade 4 exposed.Moreover, when the hairs around the brushroll 201 need to be cut off,all the safety protection devices 3 need to be toggled at the same timeto make them disengage from the pedal 2, such that the pedal 2 isreleased and then is rotated to the second position to expose the blade4, thereby cutting off the hairs around the brushroll 201. In thisprocess, if only some of the safety protection devices 3 are toggled,the pedal 2 cannot move to the second position, thus further ensuringthe security of the user.

For the charging stand 100 for the vacuum cleaner 200 according toembodiments of the present disclosure, with the blade 4 in the body 1,the functionality of the charging stand 100 is expanded, and with thepivotable pedal 2 and the at least two safety protection devices 3, thesafety may be effectively guaranteed during operation of the chargingstand 100.

In an embodiment of the present disclosure, the pedal 2 is disposedhorizontally when in the first position, as shown in FIG. 2, such thatthe overall appearance of the charging stand 100 is aesthetic, and therechargeable vacuum cleaner may be horizontally placed on the pedal 2when charged. When the pedal 2 is in the second position, a front end ofthe pedal 2 is located at a lower height compared with the front end inthe first position, as shown in FIG. 3. That is, the pedal 2 can move tothe second position as long as the pedal 2 is stepped down, which bringsgreat convenience to the user. It should be noted herein that thedirection “front” refers to the direction of the charging stand 100close to the user, and the direction “rear” refers to the oppositedirection.

A rotation angle of the pedal 2 rotating from the first position to thesecond position is denoted as α, in which α satisfies 0°<α≦60°. Forexample, α may be 30°. Further, α further satisfies 1°≦α≦10°. Forexample, α may be 3° or 5°. It could be understood that a specific valueof α may be varied adaptively in the light of practical requirements,which will not be defined particularly.

When the pedal 2 is in the first position, an upper end of the blade 4is preferably lower than a lower surface of the pedal 2, and certainly,the upper end of the blade 4 may be higher than the lower surface of thepedal 2 but lower than an upper surface (not shown) of the pedal 2.

As shown in FIGS. 1 and 7, the opening 21 extends along a left-rightdirection; a length direction of the blade 4 is identical to theextension direction of the opening 21 and identical to a lengthdirection of the brushroll 201. Thus, the blade 4 can fully cut off thehairs around the brushroll 201.

As shown in FIG. 13, the body 1 has a base 11, and the blade 4 isdisposed on the base 11. The blade 4 is configured to cut off the hairswound around the brushroll of the vacuum cleaner. In the hair-cuttingprocess, the upper end of the blade 4 is in contact with a brushrollboss 202 (not shown) on the brushroll, so as to cut off the hairs aroundthe brushroll boss 202. In such a case, the vacuum cleaner may be arechargeable vacuum cleaner or other types of vacuum cleaners.

Referring to FIG. 13, an elastic member 42 is disposed between the blade4 and the base 11, and optionally is made of soft rubber, but is notlimited thereto. Therefore, during operation of the charging stand 100,a height of the blade 4 may be automatically adjusted by means of theelastic member 42 when the blade 4 is in over-interference contact withthe brushroll boss 202 during rotation, such that the blade 4 does notcome into excessive contact with the brushroll boss 202, thereby greatlyreducing the accuracy of positioning the blade 4, decreasing the cost,and improving the product qualification rate.

In some embodiments of the present disclosure, as shown in FIG. 13, thecharging stand 100 further includes a blade holder 41 that is disposedon the base 11. The blade holder 41 is disposed on an inner wall (abottom wall in FIG. 2) of the base 11. The blade 4 is disposed on theblade holder 41, for example, may be inserted into the blade holder 41.Therefore, by providing the blade holder 41, the blade 4 may be mountedon the base 11 conveniently and reliably. Preferably, the blade 4 isdisposed vertically, so as to cut off the hairs wound around thebrushroll effectively.

The elastic member 42 is disposed between the blade 4 and the bladeholder 41, and/or between the blade holder 41 and the base 11.Specifically, the elastic member 42 may be disposed only between theblade 4 and the blade holder 41, or may be disposed only between theblade holder 41 and the base 11, or may be disposed both between theblade 4 and the blade holder 41 and between the blade holder 41 and thebase 11. For example, referring to FIG. 13, the elastic member 42 isdisposed between the blade holder 41 and the base 11, and an upper endof the elastic member 42 is connected to a lower end of the blade holder41.

Specifically, when the elastic member 42 is disposed between the bladeholder 41 and the base 11, an accommodating groove 111 is defined in thebase 11 and configured to accommodate the elastic member 42. Referringto FIG. 13, a part of the inner wall of the base 11 is recessed towardsa direction away from a center of the base 11, so as to define theaccommodating groove 111. Thus, the elastic member 42 may be assembledand disassembled conveniently, and the position of the elastic member 42may be stabilized, thereby improving the overall performance of thecharging stand 100.

Optionally, an upper surface of the elastic member 42 is higher than anupper surface of the base 11. Referring to FIG. 13, the upper surface ofthe elastic member 42 is higher than an upper surface of the bottom wallof the base 11. Thus, it is convenient to adjust the height of the blade4.

The pedal 2 is provided with a stopping piece 26, and the opening 21 isdefined in the stopping piece 26. For example, referring to FIGS. 14 to16, the stopping piece 26 is preferably disposed adjacent to a groundbrush mouth of the vacuum cleaner 200 and located below the ground brushmouth, in which case a distance between the stopping piece 26 and theground brush mouth is relatively short. Therefore, in the hair-cuttingprocess, the cut hairs thrown by the brushroll 201 fall on the stoppingpiece 26 and cannot exceed a dust suction range of the vacuum cleaner200, such that it is possible to prevent the cut hairs from falling intoany other place beyond the dust suction range of the vacuum cleaner 200and hence avoid secondary pollution.

Optionally, the stopping piece 26 is horizontally disposed. The cuthairs falling onto the stopping piece 26 can be prevented fromgathering, which facilitates suction of the hairs on the stopping piece26 into a dust cup by the vacuum cleaner 200, thereby improving thevacuuming efficiency. In addition, materials may be saved, therebylowering the material cost.

As shown in FIG. 15, a lower surface of a part, adjacent to the opening21, of the stopping piece 26 defines a clearance groove 261. Further, adistance between an inner wall of the clearance groove 261 and an uppersurface of the stopping piece 26 is gradually decreased in a directiontowards a center of the opening 21. That is, a thickness of a part ofthe pedal 2 adjacent to the opening 21 is gradually reduced in adirection towards the opening 21. Thus, the blade 4 can be preventedform touching the stopping piece 26, the service life of the stoppingpiece 26 can be prolonged, and the usage cost can be reduced.Optionally, the stopping piece 26 may be made of soft rubber, but is notlimited thereto. For example, the stopping piece 26 may be made of rigidplastics, as long as the stopping piece 26 is able to guarantee that thehairs thrown by the brushroll 201 fall within the dust suction range ofthe vacuum cleaner 200, which will not be limited specifically.

As shown in FIGS. 2, 3 and 10, the lower surface of the pedal 2 isprovided with at least one reinforcing rib 25. For example, a pluralityof reinforcing ribs 25 may be provided, and disposed to the lowersurface of the pedal 2 and spaced apart evenly. Thus, the strength ofthe pedal 2 may be guaranteed effectively by providing the reinforcingribs 25.

In an embodiment of the present disclosure, when the blade 4 extends outof the opening 21, the blade 4 can cut off the hairs around thebrushroll 201 of the vacuum cleaner 200 placed on the pedal 2. Referringto FIG. 9 in combination with FIG. 10, the charging stand 100 furtherincludes a microswitch 5 that is disposed within the body 1. When thepedal 2 is in the second position, the microswitch 5 is triggered tomake the charging stand 100 stop charging and rotate the brushroll 201.

For example, as shown in FIG. 10, the pedal 2 is pivotably connected inthe body 1 through a pivot shaft 22; the microswitch 5 is disposed at arear portion of the charging stand 100 and located above the pedal 2.When the pedal 2 is stepped down, a rear end of the pedal 2 is tiltedupwards and triggers the microswitch 5, such that the microswitch 5 mayswitch off the charging function of the charging stand 100 to stopcharging the rechargeable vacuum cleaner placed on the pedal 2, andtransmit a signal to the rechargeable vacuum cleaner to make the vacuumcleaner operate. At this time, the brushroll 201 is rotated and theblade 4 implements the hair-cutting process. It should be noted hereinthat the specific structure and working principle of the microswitch 5are well known and hence will not be elaborated in detail.

In a specific embodiment of the present disclosure, as shown in FIGS. 2to 5, the pedal 2 has a first end and a second end. The first end of thepedal 2 is pivotably connected to the body 1 through the pivot shaft 22,and an elastic resetting member 23 is provided between the second end ofthe pedal 2 and the body 1. The elastic resetting member 23 isconfigured to normally push the pedal 2 towards the first position, thatis, the pedal is normally held in the first position. Optionally, theelastic resetting member 23 is configured as a spring.

For example, as shown in FIGS. 2 to 5, the pedal 2 extends along afront-rear direction. The first end of the pedal 2 is the rear endthereof, and the second end of the pedal 2 is the front end thereof. Therear end of the pedal 2 is pivotably connected to the body 1 through thepivot shaft 22 extending along the left-right direction. The spring isdisposed at the front end of the pedal 2 and located between the lowersurface of the pedal 2 and a bottom wall of the body 1. The spring isconfigured to normally push the pedal 2 upwards to keep the pedal 2 in ahorizontal position.

Further, a side of the body 1 adjacent to the second end of the pedal 2is provided with a position-limiting member 24, and theposition-limiting member 24 is located at a side of the pedal 2 awayfrom the elastic resetting member 23. For example, as shown in FIGS. 1to 3, the position-limiting member 24 is configured as a baffle, and thebaffle is disposed at a front side of the body 1 and abuts against theupper surface of the pedal 2, so as to prevent the pedal 2 from rotatingupwards under the action of the spring.

As shown in FIG. 4, when the rechargeable vacuum cleaner needs to becharged, the rechargeable vacuum cleaner may be placed on the pedal 2 ofthe charging stand 100 so as to be charged. When the hairs need to becut off, after the vacuum cleaner 200 (not limited to the rechargeablevacuum cleaner in this case) is placed onto the pedal 2, a front portionof the vacuum cleaner 200 may be pressed down to drive the front end ofthe pedal 2 to move downwards, such that the blade 4 may extend into theopening 21 of the pedal 2, and then the vacuum cleaner 200 is actuatedto rotate the brushroll 201 (for example, realized by means of themicroswitch 5), thereby implementing the hair-cutting process, as shownin FIG. 5.

Therefore, by providing the charging stand 100, it is attainable to cutoff the hairs automatically, that is, the user may implement thehair-cutting process without disassembling the brushroll 201, whichbrings great convenience to the user.

In a specific embodiment of the present disclosure, a top of the body 1is open; the pedal is disposed within the body 1; the upper surface ofthe pedal 2 is lower than an upper end face of the body 1; the pedal 2is spaced apart from the bottom wall of the body 1; an accommodatingspace is defined between the pedal 2 and the body 1; and the blade 4,the spring and the like may be placed in the accommodating space.

In an embodiment of the present disclosure, as shown in FIGS. 6 to 8,each safety protection device 3 includes a safety protection member 31and a resetting member 32. The safety protection member 31 is disposedat a side face of the pedal 2, and defines a fitting groove 311 in whichan edge of the pedal 2 is fitted. The resetting member 32 is disposedbetween the safety protection member 31 and the body 1, and configuredto normally push the safety protection member 31 towards a center of thepedal 2. Optionally, the resetting member 32 is configured as aresilient sheet or a spring. Thus, by providing the safety protectionmember 31, the edge of the pedal 2 may be fitted in the fitting groove311 of the safety protection member 31, so as to prevent the pedal 2from moving to the second position and hence prevent the blade 4 frombeing exposed; moreover, by providing the resetting member 32, when noexternal force is exerted on the safety protection member 31, the safetyprotection member 31 enables the edge of the pedal 2 to be fitted in thefitting groove 311 under the action of the resetting member 32, so as toplay a role of safety protection.

As shown in FIG. 6, the safety protection member 31 is pivotablyconnected to the body 1, and has a first end (e.g. an upper end in FIG.6) and a second end (e.g. a lower end in FIG. 6). The fitting groove 311is defined in the second end of the safety protection member 31. Whenthe first end of the safety protection member 31 is toggled, the secondend of the safety protection member 31 moves away from the center of thepedal 2 to disengage the edge of the pedal 2 from the fitting groove311.

In normal situations, the safety protection member 31 is verticallydisposed, and a side of the fitting groove 311 towards the center of thepedal 2 is open and fitted with the edge of the pedal 2. In such a case,when the pedal 2 is stepped down, since the edge of the pedal 2 abutsagainst an inner wall of the fitting groove 311, the pedal 2 cannot moveto the second position, i.e. the blade 4 cannot extend out of theopening 21, which improves safety. When the hairs need to be cut off,for example, the first end of the safety protection member 31 may betoggled downwards, such that the fitting groove 311 in the second end ofthe safety protection member 31 moves away from the pedal 2 anddisengaged from the pedal 2. At this time, the pedal 2 is stepped downand hence is able to move to the second position, such that the blade 4extends out of the opening 21 to implement the hair-cutting process.

As shown in FIG. 6, when the pedal 2 is in the first position, the firstend of the safety protection member 31 extends out of an inner side faceof the body 1 and is located above the pedal 2. Thus, it is convenientto toggle the first end of the safety protection member 31.

Further, the first end of the safety protection member 31 has a guidesurface configured to toggle the first end of the safety protectionmember 31. Optionally, the guide surface is constructed to extendobliquely towards the center of the pedal 2 from up to down. Forexample, the guide surface is formed as an oblique plane or an obliquecurved surface, extending obliquely towards the center of the pedal 2from up to down. Thus, when the vacuum cleaner 200 is placed onto thecharging stand 100 from up to down, the first end of the safetyprotection member 31 may be toggled downwards by a side face of thevacuum cleaner 200 along the guide surface, so as to disengage the pedal2 from the safety protection member 31.

As shown in FIG. 7, two safety protection devices 3 are provided andlocated at left side and a right side of the body 1 respectively. Thus,with the two safety protection devices 3, the blade 4 may extend out ofthe charging stand 100 by toggling the two safety protection devices 3simultaneously and stepping down the pedal 2, such that.

An example provided with two safety protection devices 3 is illustratedherein. When the charging stand 100 is not used for charging, the safetyprotection members 31 of the two safety protection devices 3 are engagedwith the edges of the pedal 2 under the action of the resetting members32, in which case even if the pedal 2 is stepped down, the pedal cannotmove to the second position, i.e. the blade cannot extend out of theopening 21. Moreover, when only one safety protection device 3 istoggled and disengaged from the edge of the pedal 2, since the othersafety protection device 3 is still engaged with the edge of the pedal2, the pedal 2 still cannot move to the second position, whichguarantees the safety of the charging stand 100. When the rechargeablevacuum cleaner needs to be charged or the hairs on the vacuum cleaner200 need to be cut off, the vacuum cleaner 200 may be placed on thecharging stand 100. In this process, the safety protection members 31 ofthe two safety protection devices 3 are toggled by the vacuum cleaner200 to be disengaged from the pedal 2, such that the rechargeable vacuumcleaner may be charged. If the pedal 2 is stepped down and moves to thesecond position, the blade 4 extends out of the opening 21 of the pedal2 to cut off hairs.

Therefore, by providing the safety protection device 3, when there is noneed to perform the charging function, it is possible to avoid safetyhazards when the charging stand is accidentally triggered.

The functionality of the charging stand 100 according to embodiments ofthe present disclosure is expanded and the safety of using the chargingstand 100 is enhanced.

Other constructions and operations of the charging stand 100 accordingto embodiments of the present disclosure are well known to those skilledin the art, which will not be elaborated herein.
